Problems solved by technology

This phenomenon is common in the production process of navigation data. Frequent modification prohibits turning to data records and aggregation node intersection data. Not only is error prone, but also increases the workload of data editing, which affects the quality and efficiency of data production.

Embodiment Construction

[0013] In the navigation data production tool, the identification method of the prohibited turning attribute of the fork is realized with the help of the computer keyboard and mouse under the support of the electronic vector map with the road traffic direction information. The important thing is: the navigation data Adding an intermediate memory and an encoding circuit to the production tool, the steps of the marking method include:

[0014] A. According to the InLink and OutLink marks of each road relative to the fork P in the electronic vector map, select a road to InLink, and perform counterclockwise rotation on the OutLink road that intersects with the fork P. 1-N serial number;

[0015] B. An N-bit binary number is set as the above-mentioned selected turning restriction code for the InLink road, and the digits of this binary number are corresponding to the sequence number 1-N from the prohibition of turning to the OutLink road from the InLink road, The value of the code ...

Abstract

An identification method for turning prohibition properties of a fork road in a navigation data production tool is realized by the aid of a computer keyboard and a mouse under the support of an electronic vector map with traffic directionality information. During navigation data production, recording of turning prohibition data of the fork road is unrelated to Link ID (identification), and Main Node ID, Sub Node ID and Sub Link ID of the fork road, so that data production quality and efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the field of navigation data production, and specifically relates to a method for marking the prohibition turning attribute of a fork in a navigation data production tool. Background technique [0002] At present, in the production of known navigation data, we traditionally call the "fork" formed by one or more two-way drawn roads as "aggregation node intersection". The aggregation node intersection is actually an area (such as figure 1 shown), this area can realize the vehicle to complete the steering action according to certain rules, but in the production of navigation data, in order to keep the shape of the intersection data from deformation, and to ensure the connectivity of the road topology data in the navigation data, we will Some "paths" are virtualized at the intersection of the aggregation node, which are denoted as "Link". The part of these Links in the intersection area of ​​the aggregation node is denoted as "SubL...
